Idea. Design. Machine.

3defacto’s design department sets the foundation for long-term successful production and dynamic processes in mechanical engineering with ideal individual solutions. Our solid and well-trained designers have years of project experience and integrate quickly into existing concepts and teams. In so doing, they use precisely those techniques that bring the greatest benefit for the requirements at hand: from design with SolidWorks, customised manufacturing technology for special machines, and the new development of prototypes to component optimisation in process engineering, plant engineering, or conveyor technology.

The fact that this approach strengthens innovation and enables cost-saving, optimised production has been demonstrated by many successful projects over 20 years. Thanks to the long service record of our specialists, we can guarantee sound advice from the design engineers involved, even long after a project has been implemented. Convince yourself of the quality and skill of our specialist engineers without obligation: as a new customer you will receive a satisfaction guarantee at 3defacto.


Design it yourself or have it designed: 3defacto finds the best individual solution and offers services from a single source – from component optimisation to new developments in special mechanical engineering. All production employees are SolidWorks certified. Our services in the field of design are:
